hey guys just see what you guys think of this

my cousin has a r34 gt-t manual ( stock ) other then a pod filter and cat back

and one of my mates just bought one with a exaust, pod and been boosted to 10psi

but it was a auto and now converted to a manaul but its a shit load slower!!!! even though its running more boost..

how is this possibal are the auto's de tunned?

any feed back is good feed back

Yes it's me, and yes that R34 is slow haha.

I just can't wait till I get a turbo-back exhaust fitted and the engine/turbo should rev quicker and be much more responsive.

But yes, i would also like to know what other people think. Are the automatic R34 GT-T Skyline's de-tuned from factory just like the automatic S15 200sx/Silvia's are?

Cheers for any help :ninja:

De-tuned? No

The Auto has a different ratio diff to the manual, That would play a part. Also engine condition, service history, type of fuel being used, condition of fuel pump etc etc

but to play a big enough part that the one that had the conversion was running a singel stage boost controler and significantly slower?

Jace, I honestly reckon it is due to my car having the standard exhaust. Once I get the turbo-back exhaust, power fc, electronic boost controller and a tune i should be looking around the 270-280rwhp mark.

you wont get 270-280 with just those mods. The stock R34 turbo wont boost about 13psi with 14 maxing its efficiency range. I saw about 250rwhp with all those mods. I have a full turbo back apexi 80mm dump with 100mm exhaust.

Hrrm.. Maybe you just got a 34 in bad condition or something wrong with it? Mines an auto converted to manual and its perfectly fine.. havent done heaps to it, pod, zorst from the turbo back, lightened flywheel an hd clutch.. Nothing special and its got a good boot to it running stock boost.

Have you had it serviced? does it do anything odd? ie: idle funny, backfire etc??

Hope you work out what it is mate, maybe its been boosted and not tuned so afr are rooted?

Good luck buddy hope you work out what it is.

Also - be warned that if you need to upgrade the clutch (like i just have) the japs usually convert with an r33 gearbox so you would need a different clutch to a 34 clutch (one is pulltype and the other is push type).

Could cause you some drama if you get the wrong one first because I've been told its not easy to determine until you drop the gearbox out.

Nah nothing funny about it.

I need to service it (plugs, oil, filters, throttle body clea, etc) but nothing unusual.

I know i can get close to 280rwhp with the usual mods (Z32afm, boost controller, exhaust, intake, fmic, computer, tuned correctly), as my old skyline was making 265rwhp with those mods :)

Yeah it does backfire, only because I unbolted the cat from the rest of the exhaust and have been driving around like that (i got bored of a dead quiet exhaust and did this till i get my proper exhaust haha)

    • Read the ECU for fault codes or have someone else do it. A faulty coolant temperature sender is usually listed in ECUs. If the sensor itself is not busted it can also be a bad ground connection. Or in a really unlucky case, damaged wiring.
    • Can't be a Futjitsubo as those are made with a flex piece and Reimax is smaller in pipe diameter. If anything it is closest to a Mines pipe, but evidently it is not an actual Mines pipe.   Classic word humor
    • Alright I will try to not forget.   As GTSboy replied to you already, problem is mainly the mismatch between the actual exhaust part and the denomination in the papers. That basically just looks like tampering to a cop, if they were to check your car and notice. If it had been done right they would have clarified it to be a custom pipe and just given it a certain part number that you have to engrave or weld onto the pipe. I will definitely inquire on what to do. Changing the pipe wouldn't be my favorite solution as it costs a bunch of money and the cat was fitted with the front pipe and exhaust under the car, and if the front pipe flange does not sit in the OEM location the cat will need to be refit for any other pipe to work. It also usually doesn't need a brand name or something like that, but more something like a part number. Usually for exhaust parts, on silencers and cat units specifically, there is a badge that reads the certificate number that belongs to these exhaust parts under EU regulation. You get these numbers after you put a part or group of parts through the tedious testing according to EU vehicle legislation and they pass. You can find these "part numbers" on various parts throughout a EU vehicle. On windows, headlights, engine parts, seat belts and so on. All these parts have gone through standardized testing and acquired a so called ECE or EG Certificate that makes them legal to use by themselves in all countries that adhere to these standards. You can also not alter these parts in any way, if you do they become illegal. An example for stampings on an exterior lighting part, the people who need to know can find the documentation for this unit in a database. I do not know what all the standards and so on mean.
    • If that was the case I suppose you could call it "Mein's" brand....  ... I'll see myself out... 😅
